CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 299,535, dated June 3, 1884-.

Application filed March 27, 1884.

To all whom it may concern.-

Be it known that I, IVIAHLON HARROLD, a citizen of the United States, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Car- Couplings; and I do hereby declare the following to'be a full,

ing simplicity and economy in construction and effectiveness in operation; and to this end the invention consists in novel features of construction and combination and arrangement of parts, all as will be hereinafter fully described, and set forth in the claim hereto annexed.

Referring to the accompanying, drawings, Figure 1 represents a longitudinal vertical central section through the adjacent drawheads of two cars, showing my improvements applied, one draw-head showing the link coupled and the other ready for coupling; Fig. 2, ahorizontal section through one of the draw-heads with the locking devices removed.

In the drawings, A A represent the ordinary draw-heads, having the usual flaring mouths.

B represents a longitudinal slot through the bottom portion or floor of the draw-head, and in which is pivoted a lever, O, bya transverse bolt, D, having one of its ends square, and which fits in a corresponding recess in the side of the draw-head, thus preventing said bolt from turning, and thereby obviating the loss of the usual fastening screw-nuts, and the consequent loss of the fastening-bolt, due to rattling and jarring incident in this class of couplers, the transverse bolt in the present instance being secured in position by a pin, (1, passing through the opposite end thereof, as shown in Fig. 2. The lever G has its lower end projecting downward through the slot 13, while its (N0 model.)

upper end projects above the slot into a longitudinal recess, E, formed to correspond tothe oscillating movement of the lever. The lever has pivotally connected to its lower end a weight, F, by which it is always retained in a vertical position, as shown in Fig. l.

G represents a locking-pin passing down through an opening in the draw-head, said pin being of such length as only to reach thelower end of the recess E, and thereby never in position to be struck by the coupling-link H, said pin always retaining its. position, as shown, (except when uncoupling,) and only acting as a locking-pin to prevent the lever from being drawn forward and permitting the uncoupling of the cars when under motion.

By my improved coupling I am enabled to apply it in connection with all constructions of draw-heads where a locking pin and link are used, and also in connection with cars of different heights, where the usual bent links are used.

The coupling of cars with my improved coupling is readily understood by reference to Fig. 1, and in uncoupling it is only necessary 7 to raise the locking-pin, when the link, being drawn forward, will oscillate the lever G forward, so as to readily slip or pass by it, when the lever will resume its normal vertical position, so that upon the pin being again inserted the parts are again in position for coupling.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In an automatic car coupler, the combination of the draw-head having the slot B and recess E, the weighted and pivoted lever 0, extending up into said recess, and a lockingpin, G,with which said lever engages, substantially in the manner as and for the purpose herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

MAHLON HARROLD.
